The Relation of Mollusks to Fish in Oneida Lake 241 
Ataxv, species not indicated, was observed in 35 species of 
mussels, including Strophitus edentulus, Anodonta grandis, 
Lampstlis luteola, and L. ligamentina which occur in Oneida 
Lake (p. 409). 
Conchophthirus hirtus Ehrbg, and C. anodonte Ehrbeg, 
cihate infusorians were observed in 30 species of mussels, 
including the four species mentioned in the last paragraph 
which occur in Oneida Lake (p. 407, 409). 
Chetogaster limnai yon Baer, an oligocheete, was observed 
in the kidneys and on various parts of the surface of 5 species 
of mussels, none of which occur in Oneida Lake (p. 407, 
409), 
Wilson and Clark (1912, p. 11, 12, et seq.) examined many 
mussels from the Kankakee River basin, Indiana and Illinois, 
a number of which were infested with parasites, including 
Atax, Coltylaspis imsignis, Aspidogaster conchicolor, and 
several distomids. Of the species of mussels infested, 
Anodonta grandis and Lampsilts luteola occur in Oneida 
Lake. 
In an earlier publication these authors (1912, pp. 61-72) 
discuss the parasites of the mussels inhabiting the Maumee 
River. The parasites listed which infest species of mussels 
that occur in Oneida Lake are indicated below : 
Cotylaspis insignis Leidy, in Anodonta grandis, Lamp- 
silis luteola and L. ligamentina (p. 61). 
Aspidogaster conchicolor von Baer, in Anodonta grandis 
and Lampsilis ligamentina (p. 61). 
Marginal-eyst Distomid, in Lampsilis ligamentina (p. 62). 
Distomid of Osborn, in Anodonta grandis (p. 64). 
Distomid of Kelly, in Lampsilis ligamentina (p. 68). 
Bucephalus polymorphus von Baer, in Lampsilis luteola. 
It is of importance to note that the mature form of Buce- 
phalus is Gasterostomum fimbriatum yon Siebold, which
